We're building a project car with an M120 engine base and the original spark setup was with plug leads and distributors, but we're wanting to go to the later version with what look like they are coil on plug setup.
My questions are.........
1. are the packs that are fitted to the later models internally ignited ? ie don't have an external ignitor pack somewhere ?
2. if they are internally ignited...... does anyone have a pin out for the coils ?
3. does anyone know where I can source the connectors for the coils so we can terminate them onto our ECU loom (Motec M150)
These are an example of the coil packs I'm talking about...  Ignition Coil for MERCEDES W140 600 S600 6.0 M120 Petrol Delphi | eBay
Thanks very much in advance. |
1) The primary of the coil(The coil is a step up transformer with a primary and a secondary), and each bank has the drive has its drive transistors at the computer module which drive each coil.
2) They can be found here:
NEXEDGE StarFinder
A)Choose the W140
B) WebETM W/Starfinder
C) Mixture formulation
D) Documents 07.61-U-2000XD & 07.61-U-2000XF
E) You may not see the diagrams, but print legend and diagnostics. I Uploaded the diagrams.
3)Mercedes sells the connectors and pins, but one can yank the connectors from a junk M119 harness from a self-serve junk yard.
Hope it helps
